BioAllers Sinus and Allergy: What it Contained in 2013 vs 2021, and its place in Homeopathy or Herbalism. Does it work?

 Whether it’s for tree pollen, yeast, mold, or dust, I wanted to know if the homeopathic medicine product BioAllers would work, and if so, how it works, and where it stood pharmacologically. I’ve now noticed that BioAllers in 2013 had a different formula than it does now in 2021.
